Application of virtual instrument technology in Dynamic resolution detection of Aerial Camera
The dynamic resolution detection system of aerial camera is used to simulate the motion state of ground object relative to aircraft flight in the laboratory, realizing the resolution detection of aerial camera in dynamic photography. In this paper, the virtual instrument technology and motion control technology of dynamic resolution detection system based on LABVIEW are mainly studied, the movement curve of dynamic target simulation system is designed according to the image motion velocity equation of aerial camera, the friction fluctuation compensation algorithm is used to improve the conventional PID control algorithm to complete the linear motor control with high precision at uniform velocity section of the motion curve. The system realizes the speed range of uniform linear motion of dynamic graphics from 10~1000mm/s, the instantaneous velocity error of uniform velocity section is less than 3mm/s and the average velocity fluctuation error is less than 0.1%.
